    Answer: The point (5,7) is on the line 5x+6y = 67

    =====================================================

    Explanation:

    (5,7) means x = 5 and y = 7 pair up

    Plug in those values to get…

    5x + 6y = 67

    5*5 + 6*7 = 67

    25 + 42 = 67

    67 = 67

    We get the same number on both sides after fully simplifying. This means the equation is true. A true equation in the last step means the first equation is true when (x,y) = (5,7).

    Therefore, the point (5,7) is a solution and it is on the line 5x+6y = 67.
